Dalton's idea that atoms cannot be divided into smaller parts was disproved by the discovery of what?
Dalton's idea that atoms are indivisible was disproven by the discovery of subatomic particles, such as electrons, protons, and neutrons. These particles were identified through experiments in the late 19th and early 20th centuries, revealing that atoms are, in fact, composed of smaller components. Additionally, the discovery of nuclear reactions demonstrated that atoms could be split, leading to the release of energy and further challenging Dalton's original postulate.

Did JJ Thomson experiments that showed that atoms cannot be divided into smaller particles?
Yes, J.J. Thomson's experiments using cathode rays led to the discovery of the electron and the plum pudding model of the atom. This model suggested that atoms are not indivisible, but composed of smaller particles.

Which tenet of Daltons atomic theory did Thomson disprove?
Atoms cannot be divided into smaller particles.
Which one of daltons principles were contradicted by jj Thompson?
Dalton's principle that atoms are indivisible and cannot be further subdivided was contradicted by J.J. Thomson's discovery of the electron, which showed that atoms are made up of smaller subatomic particles.
What discovery contradict components of Daltons atomic theory?
These ideas are:· "All atoms of a given element are identical" : discovery of isotopes.· "A given compound always has the same relative numbers of types of atoms" : discovery of nonstoichiometric compounds.
What part of daltons atomic theory was proved incorrect?
One part of Dalton's atomic theory that was proved incorrect is the assumption that atoms are indivisible and cannot be further subdivided. The discovery of subatomic particles such as protons, neutrons, and electrons showed that atoms are made up of smaller components.

How did the discovery of electrons make it necessary to change one of Dalton's postulates?
The discovery of electrons showed that atoms were not indivisible as Dalton had proposed, but instead contained subatomic particles. This led to a revision of Dalton's postulate that atoms were the smallest, indivisible particles, as it became clear that atoms could be divided into even smaller components such as electrons.
